Aprilia rs125 warning light/ throttle position sensor problem

water pump shaft broke not turning, system not bleed when coolant was put in, thermostate not opening check all this buddy and get back to me take pipes off water pump and see if it spins , bleed the coolant by taking the bolt of the head and let the air seep out if any if pure coolant comes out put the bolt back in quickly and take the thermostate out and put in a glass off hot boiling water and look at it and see if it moves

You need to call the dealer and ask them but most of the time warranty repairs are free. When you call, ask to speak with the service department. Explain you have a 2009 and you think it is under warranty. Then describe the problem and ask how much they will charge to to LOOK at it. Then ask if it is covered under warranty and if not what the estimated charges will be. Often they don't know exact amounts until they look at the bike and figure out what is wrong with it, but looking at it should be free under warranty.

If you are not happy with their response you can find another dealer.

EFI is electronic fuel injection. Could be any number of reasons the light is on.

The warning light and EFI will disappear once you fit power valve :)

I've got 2008 Aprilia RS125 and CDI I derestricted first.. I had warning light on until I fitted power valve.. No warning light now.
